Introduction

You can write code in VBA that reads or modifies other VBA projects, modules, or procedures. This is called extensibility because extends the editor -- you can used VBA code to create new VBA code. You can use these features to write custom procedures that create, change, or delete VBA modules and code procedures.

In order to use the code on this page in your projects, you must change two settings.

  • First, you need to set an reference to the VBA Extensibililty library. The library contains the definitions of the objects that make up the VBProject. In the VBA editor, go the the Tools menu and choose References. In that dialog, scroll down to and check the entry for Microsoft Visual Basic For Applications Extensibility 5.3. If you do not set this reference, you will receive a User-defined type not defined compiler error.

  • Next, you need to enable programmatic access to the VBA Project. In Excel 2003 and earlier, go the Tools menu (in Excel, not in the VBA editor), choose Macros and then the Security item. In that dialog, click on the Trusted Publishers tab and check the Trust access to the Visual Basic Project setting.

    In Excel 2007, click the Developer item on the main Ribbon and then click the Macro Security item in the Code panel. In that dialog, choose Macro Settings and check the Trust access to the VBA project object model.


The VBA Project that you are going to change with these procedures must be unlocked. There is no programmatic way to unlock a VBA project (other than using SendKeys). If the project is locked, you must manually unlock. Otherwise, the procedures will not work.

CAUTION: Many VBA-based computer viruses propagate themselves by creating and/or modifying VBA code. Therefore, many virus scanners may automatically and without warning or confirmation delete modules that reference the VBProject object, causing a permanent and irretrievable loss of code. Consult the documentation for your anti-virus software for details.

Objects In The VBA Extensibility Model

The following is a list of the more common objects that are used in the VBA Extensibilty object model. This is not a comprehensive list, but will be sufficient for the tasks at hand.

VBIDE
The VBIDE is the object library that defines all the objects and values that make up VBProject and the Visual Basic Editor. You must reference this library to use the VBA Extensibility objects. To add this reference, open the VBA editor, open your VBProject in the editor, and go to the Tools menu. There, choose References . In the References dialog, scroll down to Microsoft Visual Basic for Applications Extensibility 5.3 and check that item in the list. You can add the reference programmatically with code like:

    ThisWorkbook.VBProject.References.AddFromGuid _
        GUID:="{0002E157-0000-0000-C000-000000000046}", _
        Major:=5, Minor:=3

VBE
The VBE refers to the Visual Basic Editor, which includes all the windows and projects that make up the editor.

VBProject
A VBProject contains all the code modules and components of a single workbook. One workbook has exactly one VBProject. The VBProject is made up of 1 or more VBComponent objects.

VBComponent
A VBComponent is one object within the VBProject. A VBComponent is a code module, a UserForm, a class module, one of the Sheet modules, or the ThisWorkbook module (together, the Sheet modules and the ThisWorkbook module are called Document Type modules.. A VBComponent is of one of the following types, identified by the Type property. The following constants are used to identify the Type. The numeric value of each constant is shown in parentheses.

  • vbext_ct_ClassModule (2): A class module to create your own objects. See Class Modules for details about classes and objects.
  • vbext_ct_Document (100): One of the Sheet modules or the ThisWorkbook module.
  • vbext_ct_MSForm (3): A UserForm. The visual component of a UserForm in the VBA Editor is called a designer.
  • vbext_ct_StdModule (1): A regular code module. Most of the procedures on this page will work with these types of components.


CodeModule
A CodeModule is the VBA source code of a VBComponent. You use the CodeModule object to access the code associated with a VBComponent. A VBComponent has exactly one CodeModule.

CodePane
A CodePane is an open editing window of a CodeModule.

 

Referencing VBIDE Objects

The code below illustrate various ways to reference Extensibility objects.

Dim VBAEditor As VBIDE.VBE
Dim VBProj As VBIDE.VBProject
Dim VBComp As VBIDE.VBComponent
Dim CodeMod As VBIDE.CodeModule

Set VBAEditor = Application.VBE
‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘
Set VBProj = VBAEditor.ActiveVBProject
‘ or
Set VBProj = Application.Workbooks("Book1.xls").VBProject
‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘
Set VBComp = ActiveWorkbook.VBProject.VBComponents("Module1")
‘ or
Set VBComp = VBProj.VBComponents("Module1")
‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘
Set CodeMod = ActiveWorkbook.VBProject.VBComponents("Module1").CodeModule
‘ or
Set CodeMod = VBComp.CodeModule

 

In the code and descriptions on this page, the term Procedure means a Sub, Function, Property Get, Property Let, or Property Set procedure. The Extensibility library defines four procedures types, identified by the following constants. The numeric value of each constant is shown within parentheses.

  • vbext_pk_Get (3). A Property Get procedure.
  • vbext_pk_Let (1). A Property Let procedure.
  • vbext_pk_Set (2). A Property Set procedure.
  • vbext_pk_Proc (0). A Sub or Function procedure.

The rest of this page describes various procedures that modify the various objects of a VBProject.

Ensuring The Editor In Synchronized

The VBA editor is said to be "in sync" if the ActiveVBProject is the same as the VBProject that contains the ActiveCodePane. If you have two or more projects open within the VBA editor, it is possible to have an active code pane open from Project1 and have a component of Project2 selected in the Project Explorer window. In this case, the Application.VBE.ActiveVBProject is the project that is selected in the Project window, while Application.VBE.ActiveCodePane is a different project, specifically the project referenced by Application.VBE.ActiveCodePane.CodeModule.Parent.Collection.Parent.

You can test whether the editor in in sync with code like the following.

Function IsEditorInSync() As Boolean
‘=======================================================================
‘ IsEditorInSync
‘ This tests if the VBProject selected in the Project window, and
‘ therefore the ActiveVBProject is the same as the VBProject associated
‘ with the ActiveCodePane. If these two VBProjects are the same,
‘ the editor is in sync and the result is True. If these are not the
‘ same project, the editor is out of sync and the result is True.
‘=======================================================================
    With Application.VBE
    IsEditorInSync = .ActiveVBProject Is _
        .ActiveCodePane.CodeModule.Parent.Collection.Parent
    End With
End Function

You can force synchronization with code like the following. This will set the ActiveVBProject to the project associated with the ActiveCodePane.

Sub SyncVBAEditor()
‘=======================================================================
‘ SyncVBAEditor
‘ This syncs the editor with respect to the ActiveVBProject and the
‘ VBProject containing the ActiveCodePane. This makes the project
‘ that conrains the ActiveCodePane the ActiveVBProject.
‘=======================================================================
With Application.VBE
If Not .ActiveCodePane Is Nothing Then
    Set .ActiveVBProject = .ActiveCodePane.CodeModule.Parent.Collection.Parent
End If
End With
End Sub

 

Adding A Module To A Project

This code will add new code module named NewModule to the VBProject of the active workbook. The type of VBComponent is specified by the value of the parameter passed to the Add method.

    Sub AddModuleToProject()
        Dim VBProj As VBIDE.VBProject
        Dim VBComp As VBIDE.VBComponent
        
        Set VBProj = ActiveWorkbook.VBProject
        Set VBComp = VBProj.VBComponents.Add(vbext_ct_StdModule)
        VBComp.Name = "NewModule"
    End Sub

 

Adding A Procedure To A Module

This code will add a simple "Hello World" procedure named SayHello to the end of the module named Module1.

    Sub AddProcedureToModule()
        Dim VBProj As VBIDE.VBProject
        Dim VBComp As VBIDE.VBComponent
        Dim CodeMod As VBIDE.CodeModule
        Dim LineNum As Long
        Const DQUOTE = """" ‘ one " character

        Set VBProj = ActiveWorkbook.VBProject
        Set VBComp = VBProj.VBComponents("Module1")
        Set CodeMod = VBComp.CodeModule
        
        With CodeMod
            LineNum = .CountOfLines + 1
            .InsertLines LineNum, "Public Sub SayHello()"
            LineNum = LineNum + 1
            .InsertLines LineNum, "    MsgBox " & DQUOTE & "Hello World" & DQUOTE
            LineNum = LineNum + 1
            .InsertLines LineNum, "End Sub"
        End With
    
    End Sub

 

Copy A Module From One Project To Another

There is no direct way to copy a module from one project to another. To accomplish this task, you must export the module from the Source VBProject and then import that file into the Destination VBProject. The code below will do this. The function declaration is:

Function CopyModule(ModuleName As String, _
    FromVBProject As VBIDE.VBProject, _
    ToVBProject As VBIDE.VBProject, _
    OverwriteExisting As Boolean) As Boolean

ModuleName is the name of the module you want to copy from one project to another.

FromVBProject is the VBProject that contains the module to be copied. This is the source VBProject.

ToVBProject is the VBProject in to which the module is to be copied. This is the destination VBProject.

OverwriteExisting indicates what to do if ModuleName already exists in the ToVBProject. If this is True the existing VBComponent will be removed from the ToVBProject. If this is False and the VBComponent already exists, the function does nothing and returns False.

The function returns True if successful or False is an error occurs. The function will return False if any of the following are true:

  • FromVBProject is nothing.
  • ToVBProject is nothing.
  • ModuleName is blank.
  • FromVBProject is locked.
  • ToVBProject is locked.
  • ModuleName does not exist in FromVBProject.
  • ModuleName exists in ToVBProject and OverwriteExisting is False.

The complete code is shown below:

Function CopyModule(ModuleName As String, _
    FromVBProject As VBIDE.VBProject, _
    ToVBProject As VBIDE.VBProject, _
    OverwriteExisting As Boolean) As Boolean
    ‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘
    ‘ CopyModule
    ‘ This function copies a module from one VBProject to
    ‘ another. It returns True if successful or  False
    ‘ if an error occurs.
    ‘
    ‘ Parameters:
    ‘ --------------------------------
    ‘ FromVBProject         The VBProject that contains the module
    ‘                       to be copied.
    ‘
    ‘ ToVBProject           The VBProject into which the module is
    ‘                       to be copied.
    ‘
    ‘ ModuleName            The name of the module to copy.
    ‘
    ‘ OverwriteExisting     If True, the VBComponent named ModuleName
    ‘                       in ToVBProject will be removed before
    ‘                       importing the module. If False and
    ‘                       a VBComponent named ModuleName exists
    ‘                       in ToVBProject, the code will return
    ‘                       False.

Creating An Event Procedure

This code will create a Workbook_Open event procedure. When creating an event procedure, you should use the CreateEventProc method so that the correct procedure declaration and parameter list is used. CreateEventProc will create the declaration line and the end of procedure line. It returns the line number on which the event procedure begins.

    Sub CreateEventProcedure()
        Dim VBProj As VBIDE.VBProject
        Dim VBComp As VBIDE.VBComponent
        Dim CodeMod As VBIDE.CodeModule
        Dim LineNum As Long
        Const DQUOTE = """" ‘ one " character

        Set VBProj = ActiveWorkbook.VBProject
        Set VBComp = VBProj.VBComponents("ThisWorkbook")
        Set CodeMod = VBComp.CodeModule
        
        With CodeMod
            LineNum = .CreateEventProc("Open", "Workbook")
            LineNum = LineNum + 1
            .InsertLines LineNum, "    MsgBox " & DQUOTE & "Hello World" & DQUOTE
        End With
    End Sub

 

Deleting A Module From A Project

This code will delete Module1 from the VBProject. Note that you cannot remove any of the Sheet modules or the ThisWorkbook module. In general, you cannot delete a module whose Type is vbext_ct_Document.

    Sub DeleteModule()
        Dim VBProj As VBIDE.VBProject
        Dim VBComp As VBIDE.VBComponent
    
        Set VBProj = ActiveWorkbook.VBProject
        Set VBComp = VBProj.VBComponents("Module1")
        VBProj.VBComponents.Remove VBComp
    End Sub

 

Deleting A Procedure From A Module

This code will delete the procedure DeleteThisProc from the Module1. You must specify the procedure type in order to differentiate between Property Get, Property Let, and Property Set procedure, all of which have the same name.

    Sub DeleteProcedureFromModule()
        Dim VBProj As VBIDE.VBProject
        Dim VBComp As VBIDE.VBComponent
        Dim CodeMod As VBIDE.CodeModule
        Dim StartLine As Long
        Dim NumLines As Long
        Dim ProcName As String
        
        Set VBProj = ActiveWorkbook.VBProject
        Set VBComp = VBProj.VBComponents("Module1")
        Set CodeMod = VBComp.CodeModule
    
        ProcName = "DeleteThisProc"
        With CodeMod
            StartLine = .ProcStartLine(ProcName, vbext_pk_Proc)
            NumLines = .ProcCountLines(ProcName, vbext_pk_Proc)
            .DeleteLines StartLine:=StartLine, Count:=NumLines
        End With
    End Sub

 

Deleting All VBA Code In A Project

This code will delete ALL VBA code in a VBProject.

    Sub DeleteAllVBACode()
        Dim VBProj As VBIDE.VBProject
        Dim VBComp As VBIDE.VBComponent
        Dim CodeMod As VBIDE.CodeModule
        
        Set VBProj = ActiveWorkbook.VBProject
        
        For Each VBComp In VBProj.VBComponents
            If VBComp.Type = vbext_ct_Document Then
                Set CodeMod = VBComp.CodeModule
                With CodeMod
                    .DeleteLines 1, .CountOfLines
                End With
            Else
                VBProj.VBComponents.Remove VBComp
            End If
        Next VBComp
    End Sub

 

Eliminating Screen Flicker During VBProject Code

When you used the Extensibility code, the VBA Editor window will flicker. This can be reduced with the code:

Application.VBE.MainWindow.Visible = False

This will hide the VBE window, but you may still see it flicker. To prevent this, you must use the LockWindowUpdate Windows API function.

    Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" _
        (ByVal ClassName As String, ByVal WindowName As String) As Long
    
    Private Declare Function LockWindowUpdate Lib "user32" _
        (ByVal hWndLock As Long) As Long


    Sub EliminateScreenFlicker()
        Dim VBEHwnd As Long
        
        On Error GoTo ErrH:
        
        Application.VBE.MainWindow.Visible = False
        
        VBEHwnd = FindWindow("wndclass_desked_gsk", _
            Application.VBE.MainWindow.Caption)
        
        If VBEHwnd Then
            LockWindowUpdate VBEHwnd
        End If
        
        ‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘
        ‘ your code here
        ‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘
        
        Application.VBE.MainWindow.Visible = False
    ErrH:
        LockWindowUpdate 0&
    End Sub

 

Exporting A VBComponent Code Module To A Text File

You can export an existing VBComponent CodeModule to a text file. This can be useful if you are archiving modules to create a library of useful module to be used in other projects.

    Public Function ExportVBComponent(VBComp As VBIDE.VBComponent, _
                FolderName As String, _
                Optional FileName As String, _
                Optional OverwriteExisting As Boolean = True) As Boolean
    ‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘
    ‘ This function exports the code module of a VBComponent to a text
    ‘ file. If FileName is missing, the code will be exported to
    ‘ a file with the same name as the VBComponent followed by the
    ‘ appropriate extension.
    ‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘‘
    Dim Extension As String
    Dim FName As String
    Extension = GetFileExtension(VBComp:=VBComp)
    If Trim(FileName) = vbNullString Then
        FName = VBComp.Name & Extension
    Else
        FName = FileName
        If InStr(1, FName, ".", vbBinaryCompare) = 0 Then
            FName = FName & Extension
        End If
    End If
    
    If StrComp(Right(FolderName, 1), "\", vbBinaryCompare) = 0 Then
        FName = FolderName & FName
    Else
        FName = FolderName & "\" & FName
    End If
    
    If Dir(FName, vbNormal + vbHidden + vbSystem) <> vbNullString Then
        If OverwriteExisting = True Then
            Kill FName
        Else
            ExportVBComponent = False
            Exit Function
        End If
    End If
    
    VBComp.Export FileName:=FName

Searching For Text In A Module

The CodeModule object has a Find method that you can use to search for text within the code module. The Find method accepts ByRef Long parameters. Upon input, these parameters specify the range of lines and column to search. On output, these values will point to the found text. To find the second and subsequent occurence of the text, you need to set the parameters to refer to the text following the found line and column. The Find method returns True or False indicating whether the text was found. The code below will search all of the code in Module1 and print a Debug message for each found occurrence. Note the values set with the SL, SC, EL, and EC variables. The code loops until the Found variable is False.

    Sub SearchCodeModule()
        Dim VBProj As VBIDE.VBProject
        Dim VBComp As VBIDE.VBComponent
        Dim CodeMod As VBIDE.CodeModule
        Dim FindWhat As String

        With CodeMod
            SL = 1

Workbook Associated With A VBProject

The Workbook object provides a property named VBProject that allows you to reference to the VBProject associated with a workbook. However, the reverse is not true. There is no direct way to get a reference to the workbook that contains a specific VBProject. However, it can be done with some fairly simple code. The following function, WorkbookOfVBProject, will return a reference to the Workbook object that contains the VBProject indicated by the WhichVBP parameter. This parameter may be a VBIDE.VBProject object, or a string containing the name of the VBProject (the project name, not the workbook name), or a numeric index, indicating the ordinal index of the VBProject (its position in the list of VBProjects in the Project Explorer window). If the parameter is any object other than VBIDE.VBProject, the code raises an error 13 (type mismatch). If the parameter does not name an existing VBProject, the code raises an error 9 (subscript out of range). If you have more than one VBProject with the default name VBAProject, the code will return the first VBProject with that name.
